Description
Technical field
The utility model relates to a kind of hand bolt self-locking formula clamps, belong to clamp art.
Background technique
Most of tipper clamps in operation process, insert usually using hand by the connection between rotating arm and pedestal vertical plate
Pin is to realize.
Common hand bolt includes hand-held part and interconnecting piece, and it is anti-that interconnecting piece, which is mostly the unchanged cylindrical body of smooth diameter,
Only hand bolt falls off during the work time, and operator is pacified in the interconnecting piece end for passing across vertical plate through-hole using spring catch
Full locking can extract hand bolt, operation after need to pulling out night bolt when dismantling although solving the problems, such as that hand bolt falls off
Low efficiency；In addition, the case where spring catch is lost after disassembly happens occasionally, make troubles to subsequent use.
Summary of the invention
The utility model provides a kind of hand bolt self-locking formula clamp, and the hand bolt in the clamp is carried out without using spring catch
Safe locking, installation and removal are convenient, can be improved working efficiency, and there is no the hidden danger that part is lost.
To achieve the goals above, the utility model provides a kind of hand bolt self-locking formula clamp, including silk axis, is sleeved on silk
Rotating arm on axis is connected to the vertical plate of a handwheel for axis upper and lower end and pressure head and pedestal and installation on the base
One, at least two through-holes, and vertical plate one, the same height of vertical plate two are opened up on vertical plate two, vertical plate one and vertical plate two respectively from top to bottom
The through-hole of degree is coaxial；
The free end of rotating arm is corresponding with vertical plate one, vertical plate two to open up at least two through-holes；
Positioning pin is successively horizontally through the through-hole on the vertical plate one, rotating arm, vertical plate two of lowest part；
Vertical plate one, rotating arm, two top sustained height of vertical plate through-hole pass sequentially through hand bolt connection；
The hand bolt be multi-diameter shaft, wherein be located at middle part interconnecting piece be reduced diameter section, the hand-held part at both ends and
It is enlarged diameter section from lock section, the junction of reduced diameter section and both ends enlarged diameter section is respectively formed ring-shaped step.
Further, described to be also connected with truncated cone-shaped convex block from lock section front end.
Further, the rotating arm includes sleeve, linkage section and downward bending section, and sleeve is set on an axis, even
Section is connect for connecting sleeve and bending section.
In the technical scheme, by by hand Plug Design be middle part be reduced diameter section, the ladder that both ends are enlarged diameter section
The junction of axis, reduced diameter section and enlarged diameter section forms ring-shaped step, when from lock section one end sequentially pass through vertical plate one, rotating arm and
After vertical plate two, pushed under the action of self weight and gravity, ring-shaped step engages with the lateral surface below two through-hole of vertical plate, is working
During will not fall off, self-locking effect is good.Hand bolt in the clamp carries out safe locking without using spring catch, when installation
The through-hole on rotating arm top need to be only aligned with the through-hole on pedestal vertical plate top, hand bolt is penetrated, when disassembly only needs apprentice
Hand slightly lifts rotating arm, make its through-hole on pedestal vertical plate on through-hole be aligned, by hand bolt extract, effectively improve
Working efficiency, and avoid part loss.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing.
As depicted in figs. 1 and 2, a kind of hand bolt self-locking formula clamp, including silk axis 1, the rotating arm being sleeved on an axis 12,
It is connected to the handwheel 3 and pressure head 4 and pedestal 5 and the vertical plate 1 being mounted on pedestal 5, vertical plate two of 1 upper and lower end of an axis
7, open up at least two through-holes on vertical plate 1 and vertical plate 27 respectively from top to bottom, and vertical plate 1,27 sustained height of vertical plate
Through-hole is coaxial；
Rotating arm 2 includes sleeve, linkage section and downward bending section, and middle sleeve is set on an axis 1, and linkage section is for connecting
Female connector cylinder and bending section, bending section are free end, and free end is corresponding with vertical plate 1, vertical plate 27, and to open up at least two logical
Hole；
Positioning pin 13 is successively horizontally through the through-hole on the vertical plate 1, rotating arm 2, vertical plate 27 of lowest part；
Vertical plate 1, rotating arm 2,27 top sustained height of vertical plate through-hole pass sequentially through hand bolt 8 connection；
Hand bolt 8 be multi-diameter shaft, wherein be located at middle part interconnecting piece 9 be reduced diameter section, the hand-held part 10 at both ends and from
